Alien diversity in SARP and beyond, perhaps? Since it's such a hot topic for now, that could be good one. Or a terrible one. Or, on the other hand, we've also got outside cultures influencing factions and the creation thereof.
EDIT: I'm in the process of finding a quiet room that I can use this weekend. I think I'm able to use an empty classroom pretty easily, I just need to check with one of the campus advisors.
